Since I'm not very tech-savy, I would like to ask for some help and advice here.

I read the GIMX tutorial for dummies, and if I understand it correctly, I could control my XBOX 360 with my PC by following that procedure. That is nice, but I need to go one stup further.

Ultimately, I want to be able to play on my Xbox with an original xbox 360 controller, while my PC registers my inputs (as if I would have plugged in the controller USB into the PC and not the Xbox). That way, I can have a program on my pc telling me what buttons I'm pressing while I am playig a game.
You could call it sniffing.

My first thought was to simply split and duplicate the Data+ and Data- cables in the USB and plug one end in the xbox, and the other end of that splitter into my pc. That way, my PC would recognize my xbox controller, but would not try to take control over it. However, people tell me this is not a solution, for some reason I do not understand.

Therefore, my second option is to use the GIMX adapter to control my xbox using my pc, and control my pc using the xbox controller:

I am reasonably sure I can get that GIMX adapter to work (using the dummies tutorial), but I am not sure if I can get the PC to forward my xbox 360 controller input into the GIMX adapter. Do you think this would work? How would I accomplish that?

Also, maybe you know better ways of splitting the controller USB cable, or sniffing the data it sends?

I haven't really worked with GIMX yet: is there some additional software menu where you can map what PC inputs are connected to which Xbox buttons?

So, for example, if I would press the spacebar on my pc, it could set it to read it like I pressed 'X' on my xbox? If there is, then I guess I would be able to map the xbox joystick inputs to the correct xbox inputs.
